Abstract

A tool includes an upper tool having a clamping shaft and an upper main body that lie on a common positioning axis, a processing tool opposite the clamping shaft that has at least one processing edge that extends at least partially along a holding-down surface of the main upper body, a lower tool having a lower main body with a rest surface for the workpiece and a lower positioning axis oriented perpendicular to the rest surface, a counter tool body on the lower main body, the counter tool body having a counter roller with at least one counter edge opposite the at least one processing edge of the processing tool, and a processing device adjacent to the at least one counter edge that has at least one curved counter surface oriented in the longitudinal direction of the processing edge of the processing tool.
